Imaging of neural activation has been used to produce maps of functional architecture and
metabolic activity. There is some uncertainty associated with the sources underlying the …

The feasibility of non-invasive analysis of brain activities was studied in the attempt to
overcome the major limitation of actual in vivo methodologies ie invasiveness. Optic fibre …

We have studied the optical properties of mammalian cell suspensions to provide a
mechanistic basis for interpreting the optical properties of tissues in vivo. Measurements of …

This work is the first to report optical intensity changes (ΔI/I≈ 0.05%) with a latency between
60 and 160ms after electrical median nerve stimulation at 5Hz detected non-invasively …

Near-infrared (NIR) optical properties of turbid media, eg, tissue, can be accurately
quantified noninvasively using methods based on diffuse reflectance or transmittance, such …

This project had two main objectives. The first of these was to design and construct a
spectroscopic instrument to monitor small changes in optical transmission across an infant's …

The goal of frequency-domain optical absorption spectroscopy is the noninvasive
determination of the absorption coefficient of a specific tissue volume. Since this allows the …

Detection of interactions between light and tissue can be used to characterize the optical
properties of the tissue. The purpose of this paper is to develop an algorithm that determines …

We have investigated the possibility of determining the optical coefficients of muscle in the
extremities with in vivo time-resolved reflectance measurements using a layered model. A …

Near-infrared (NIR) difference spectra were obtained for oxidized cytochrome c oxidase of
isolated mitochondria in vitro and of cerebral tissue in situ observed through scalp and skull …
